CONDUIT CA1? FOR ELECTRIC INSTALLATION.

Application filed October 13, 1919.

To all whom it may 0012 0am Be it known that I, VVHnnLnn H. Vienna, a citizen of the United States, residing at New London, in the county of New London and State of Connecticut, have invented a new and useful Improvement in Conduit- Caps for Electric Installation; and I do hereby declare the following, when taken in connection with the accompanying ,lrawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent, in-

Fig. 1 a view in side elevation of one form which my improved conduit-cap for electric installation may assume.

Fig. 2 a rear view thereof with the hood elevated above the bracket.

Fig. 3 a view of the device in vertical longitudinal section shown as installed with the bracket applied to the end of a conduitpipe and bolted for support to the wall of a building.

Fig. 4 a detached view of the bracket in side elevation.

Fig. 5 a corresponding plan view thereof.

My invention relates to an improved conduit-cap for electric installation, the objectbeing to produce a conduit-cap adapted to be secured to and supported by a building, pole or any other convenient means of support rather than to rely upon the conduitpipe for its support. A further object of my invention is to adapt a conduit-cap to itself support the several wires instead of supporting them independently thereof at points adjacent thereto, whereby the number of brackets and insulators employed in any given piece of installation is reduced, and also whereby the wires may be brought to gether in one cable.

With these ends in view my invention consists in a wire-supporting conduit-cap having certain details of construction as will be hereinafter described and pointed out in the claims.

In carrying out my invention as herein shown, I employ a bracket having its body 4; formed with a vertical threaded opening 5 by means of which it is screwed upon the threaded end of the conduit-pipe 6. The said body 4 is formed with a downwardly inclined water-shedding shelf 7 upon which the insulating cleats or blocks, whatever Specification of Letters Patent.

their character, are supported and to which they are secured so as to be clamped upon. the wires or cable of the installation. As shown, the shelf 7 is formed with two threaded screw-holes 8 for the reception of two clamping-screws 9 passing downward through two porcelain cleats 10 and 11, which are thus secured in inclined positions upon the inclined shelf 7 ofthe body l. Under this arrangement, any water which may find entrance into the fixture is discharged therefrom. Furthermore, the cleats may by their clamping-screws 9, 9 be so firmly clamped upon the wires or cable as to take the entire strain upon the same, whereas, heretofore, in conduit-caps of the general type being described, no provision has been made for clamping the cleats upon the wires or cable which have been sup ported at points adjacent to the fixture but not by the same.

The bracket-body 4L aforesaid is formed at its inner end with an upright installationflange 12 formed integral with it and formed, as shown, with a hole 13 for the reception of the bolt 14:, by means of which the bracket is secured directly to a building, 'pole or any other convenient point of support 15, it being intended that the main support of the bracket shall be removed from the conduit-pipe 6 which heretofore has generally been relied upon to carry the bracket unassisted by any extraneous supporting means. On the other hand, the installationfiange 12 might be adapted in some other way to be bolted or otherwise secured to a building, pole or other point of support.

The bracket as thus constructed, is housed by means of a removable hood 15, which protects the cleats and wires or cable and excludes water therefrom. The said hood, as shown, is formed at its rear end with an inturned flange 16 enclosing an arch-shaped opening and entering a rabbet or groove 17 in the rear face of the flange 16 which is shaped to fit into and fill the said archshaped opening. Screws 18 mounted in the lower edge of the hood enter notches 19 in the opposite edges of the bracket-body i. The lower corners of the side walls of the hood are formed with notches 22 setting over lateral lugs 20 projecting from the corners of the inclined shelf 7. I ma here note that the downward inclination o the said shelf provides ample clearance for the manipulation of the wrench used for bolting the flange 12 to its support. Of course the provision of the bracket with means for securing it to a building or other means of support, does not preclude its being supported exclusively by the conduit-pipe, if desired.

As shown, my improved fixture is designed for two cleats, but without departing from my invention it may be enlarged to receive a plurality of cleats, in which event the bracket would be suitably enlarged and might be provided with additional boltholes. Furthermore, if desired, the threat ed opening in the bracket for its application to a conduit-pipe may be transferred to the flange 12 if desired. I would, therefore, have it understood that I do not limit myself to the exact construction shown and described, my invention broadly comprehending a conduit-cap the bracket of which is adapted to be supported independently of the conduit-pipe and to carry insulators adapted to be clamped upon the wires or cable and to receive the strain thereof, whereby the support of the wires or cable independent of the conduit-cap is made unnecessary.

As shown, a groove 21 is formed at the juncture of the bracket-body t and its upstanding installation-flange 12 for carrying off any water that may work through the bolt-hole 13, so as to prevent water from entering the pipe.

I claim:

1. A conduit-cap for electric installation, having a one-piece bracket formed with a threaded opening for its application to a threaded conduit-pipe, and perforated for being rigidly secured to a mounting surface, and wire-gripping and insulating means mounted upon the said bracket, whereby the bracket is supported indepemt ently of the pipe which is supported by the bracket, and whereby the entire strain iniposed upon the wires is carried by the bracket and the conduit-pipe relieved of the strain upon the wires.

2. A conduit-cap for electric installation, having a one-piece bracket formed with a threaded opening for its application to a threaded conduit-pipe, and perforated for being rigidly secured to mounting surface, and wire-gripping and insulating cleats mounted upon the said bracket, whereby the bracket is supported independently of the pipe which is supported by the bracket, and whereby the entire strain imposed upon the wires is carried by the bracket and the cond,uitpipe relieved of the strain upon the wires.

3. A conduit-cap for electric installation, having a bracket formed with a threaded opening for its application to a threaded conduit-pipe, perforated for being rigidly secured to a mounting surface, and formed with a downwardly-inclined water-shedding surface, and wire-gripping and insulating means applied to the said water-shedding surface, whereby the bracket is supported independently of the pipe which is support ed by the bracket, and whereby the strains imposed upon the wires are borne by the bracket and the conduit-pipe relieved of thestrain upon the wires.

at. A conduit-cap for electric installation, having a one-piece bracket formed with a threaded opening for its application to a threaded conduit-pipe, and perforated for its rigid application to a mounting surface, wire-gripping and insulating means applied to the bracket, and a hood applied to the bracket in position to shelter the conduitpipe, whereby the bracket is supported independently of the pipe which is supported by the bracket, and whereby the conduitpipe relieveo of the strain of the Wires.

A conduit-cap for electric installation, having a one-piece bracket, the body portion of which is formed with a threaded opening for its application to a threaded conduitpipe, and with an upright installation-fiange having a perforation for rigidly securing the bracket to a mounting surface, Wiregrip iing and insulating cleats mounted upon the body portion of the bracket, and a hood applied to the bracket in position to protect the conduit-pipe, whereby the bracket is supported iniflependently of the pipe which is supported by the bracket, and whereby the entire strain imposed upon the wires is carried by the bracket and the conduit-pipe relieved of the strain upon the wires.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
